Description

Flooring material using calcium carbonate, synthetic resin and fiberglass and its manufacturing method {THE FLOORING USING CALCIUM CARBONATE, SYNTHETIC RESINS AND FIBERGLASS AND ITS MANUFACTURING METHOD}

The present invention relates to a flooring material using calcium carbonate, synthetic resin and fiberglass, and a method of manufacturing the same. More specifically, the ratio of a mixture of calcium carbonate (stone) and synthetic resin is controlled to supply the lower layer and the upper layer, and the lower layer Inserted fiberglass between the upper and upper layers, integrally formed by press work while supplying heat source to improve the curing speed, thereby forming solid flooring, stairboard, interior and exterior building materials, calcium carbonate, synthetic resin and fiberglass flooring It relates to a manufacturing method.

In general, the flooring and stairs of offices, residential facilities and various facilities for various tourism are usually made of cement concrete or flooring materials are installed indoors and outdoors.

It is well known that with the development of plywood manufacturing technology, the utilization of solid wood and the use of plywood with excellent physical properties are provided.In case of using plywood for flooring materials such as flooring or other building materials, it is again used The surface is decorated with a resin, and the surface is coated with a resin coating material to impart resistance to water resistance and scratches.

As an example of manufacturing the indoor floorboard material of this type, there is a method of manufacturing the floorboard material by adhering the veneer veneer to the upper surface of the composite with urea resin, but the manufacturing cost increases, and the water and heat resistance is very weak.

As another example, the floorboard material manufactured by pressing the melamine resin impregnated paper (LPM) at high temperature and high pressure on the upper surface of the heavy fiber board (MDF) has advantages in reducing the manufacturing cost, but is poor in water resistance and heat resistance. There are disadvantages.

In addition, the plywood or heavy fiber boards used as the base material are usually processed in a dried state, but the environment used by being installed and installed on the inner floor of a real building is caused by a change in the room temperature and humidity due to seasonal changes such as summer and winter, The internal stress caused by the shrinkage swelling action causes the connection part to be lifted or opened, and due to chemical deterioration, it is difficult to maintain the initial bonding condition as it is, resulting in weak dimensional stability and water resistance. Done. In addition, there is a floorboard veneer, but toxic chemicals are added during the preservation process, which is harmful to the human body.

On the other hand, by using reinforced floor using HDF (Hight Density Fiderboard), it is possible to click and suspend construction, but to make the surface strength strong, but it does not use natural veneer so it does not reduce natural texture and water resistance. It is vulnerable and has a heavy disadvantage.

Utility model registration No. 0399316 for solving this problem discloses an ondol floor of a wood fiber (wood particle) -polypropylene fiber composite substrate.

As the main base material of ondol floor in the prior art, WPC (Wood Fiber Poiypropylene Hiber Composite Panel) can be used to supplement water resistance, which is the biggest disadvantage of reinforced floor, and the disadvantage of plywood floor complements impact resistance, Although it provides a flooring material that can produce a natural texture effect, there is a problem that it is difficult to obtain a flooring material having a low scratch resistance and a high gloss surface due to the characteristics of the surface sheet.

In addition, in the case of conventional plywood flooring, the veneer is adhered to the plywood, then colored and coated by a roll coater, and a synthetic resin is injected into the veneer with a pressure-sensitive main tube to reinforce the surface hardness. However, in the case of coloring, since the process of coloring by the roll coater, the disadvantage of not being able to save the wood (pattern) of the wood, which is an advantage of the veneer, and the surface hardness, surface scratch resistance, wear resistance and durability, etc. Or paints such as epoxy and acrylic-based thick, there is a problem that is easily broken by lowering the flexibility because the strength is strong.

On the other hand, among several developed technologies for reinforcing surface strength, the WPC (Wood Polymer Composite) method is to finish the coating with the coat of middle, middle and top coats by increasing the strength and hardness by resin impregnating wood veneer (pattern). In some cases, a method of hardening by injecting a resin by forcing the resin into the pores and cell layers of the wood without attaching the wood veneer on the plywood may be adopted. There is a problem that a defect such as a grinding phenomenon occurs.

In contrast, in the case of plywood manufactured by the melamine resin impregnation and overlay press method, when the veneer is attached to the plywood, the overlay containing the veneer impregnated with melamine resin and aluminum oxide (Al ₂ O ₃ ) on the veneer It has a manufacturing method similar to the reinforced floor by penetrating inside the veneer with high-temperature and high-pressure presses after it is covered.This also reduces the economical efficiency in the production process due to expensive actual cost and cumbersome working methods, and veneer that the consumer wants. It is pointed out that it is difficult to obtain the surface texture by the above thin coating method.
